摘要:
A device substrate comprising a substrate having a flow channel of a liquid, wherein an internal surface of said flow channel has an area non-compatible with said liquid; said area non-compatible with the liquid is formed by a monolayer non-compatible with said liquid; and said monolayer is connected to said substrate via a covalent bond, which allows smooth flow of the liquid in the minute flow channel.

The present invention provides aligned fine particles(30) that are aligned on a substrate(32). An organic coating film(31) is bonded to surfaces of the fine particles(30) is formed on the surfaces of the fine particles(30). An organic coating film(33) bonded to a surface of the substrate(32) is formed on the surface of the substrate(32). The organic coating film(31) on the surfaces of the fine particles(31) is bonded(34) to the organic coating film(33) on the surface of the substrate(32), whereby the fine particles(31) are immobilized and aligned on the substrate(32). Thus, it is possible to align the fine particles(31) of a nanometer scale in a specific direction. When fine magnetic particles are used, a magnetic recording medium for high recording density can be obtained, and a high-density magnetic recording/reproducing apparatus can be provided.
摘要:
A medical member having active hydrogen groups such as hydroxyl, amino or imino groups at its surface, is dipped, either directly or after formation of an inner layer on its surface, into a solution. The solution is prepared by dissolving a surface active material, e.g., CF3(CF2)7 (CH2)2SiCl3 in a non-aqueous solvent. A dehydrochlorination reaction is brought about between active hydrogen groups at the surface of the member and SiCl groups of the surface active material, thus producing bonds of CF3(CF2)7(CH2)2Si(O-)3 over the entire surface. A fluorine-containing monomolecular film is formed, which is chemically (or covalently) bonded to the member surface and has a thickness at the nanometer level. Since the chemically adsorbed film is covalently bonded to the member or inner layer, it is chemically stable and difficult to separate. Excellent medical members can be obtained when the invention is applied to an artificial tooth, a joint, a bone, a blood bag, a catheter, a blood transportation tool, a dialysis equipment part, an operation thread, a medical implant and an operation tool.
摘要:
A latent image comprising a first substance formed on a substrate of a second substance having a surface tension different from a surface tension of the first substance, the first substance and the substrate having a difference of 0.1 to 100nm in height from each other. The latent image is formed by a method comprising the step of subjecting a substrate of a first substance to a chemical treatment or a physical treatment to form a surface of a second substance which has a surface tension different from a surface tension of the first substance and has a difference of 0.1 to 100nm in height from the substrate on part of the substrate. The latent image is developed by a method comprising the steps of contacting a latent image comprising a first substance formed on a substrate of a second substance having a surface tension different from a surface tension of the first substance with a third substance different from the first substance and the second substance, and applying a developing ray to the latent image.
